MKS-05 Terra-P radiation detection measurement instrument is the most popular household dosimeter in Ukraine and throughout the world. It is designed on the basis of the professional device MKS-05 TERRA, which is in operational service with the Ukrainian Army.
The dosimeter will help you to check the radiation safety of your home, place of work and leisure, car, household items, clothing construction materials, wild berries and mushrooms. Also, Ecotest Terra-P MKS-05 measures gamma background level and accumulated dose, estimates beta contamination. It is designed in a yellow shockproof housing and is compact in size.
The device is very simple to use, since it has only 2 control buttons – Threshold and Mode. To turn on the dosimeter, press and hold the Mode button for one second and dosimeter automatically enters the mode of gamma radiation measurement.
Terra-P dosimeter complies with educational requirements and is recommended by the Ministry of Education and Science of Ukraine for use as visual aids in educational establishments.

Measurement ranges and main relative errors:
– Gamma and X-ray radiation ambient dose equivalent rateµSv/h0.1…999.9;

%±(25+2/H*(10)), where H*(10) is a numeric value of measured DER equivalent to µSv/h
– Gamma and X-ray radiation ambient dose equivalentmSv0.001…9 999; ±25%
– Beta-particles flux density with possible evaluation of surface contamination by beta radionuclides (90Sr+90Y)1/(cm2×min)10…100 000
